If Indy flowed theirs in Indianapolis and you in Washington state, then I'd say those numbers are spot on. At What elevation do you think edelbrock's flow bench sits? I'd guess 1000 -1500 ft is worth 10 percent.
They both should be using corrected numbers, not actual numbers. Otherwise, you can flow a head in July and then flow it again in October and expect the numbers to be worth anything. Doesn't matter what state or continent you live on.
